Carter YF carburetor in Chrysler Products - General Posted Sunday at 12:40 PM · Edited Sunday at 04:14 PM by carbking (see edit history) Carter made hundreds of different type YF carburetors. Because the technology of the YF was light years ahead of the BBR series, the YF that fits the 218 intake manifold is too large internally, and the YF that is correct internally for the 218 won't fit the intake. Yes, it is a MUCH better carburetor. Yes, it CAN be made to fit. Yes, IF you use the correct size and modify it to fit, you WILL like it. I would suggest the aftermarket YF units that were produced for Chevrolet. 787s or 964s should work very well once you adapt the mounting. WARNING: There are some current repops (universal - one size fits all, works well on nothing) being made somewhere (but not by Carter) today (new). Good luck if you get one. Jon.
